FloatConverter

Description

The FloatConverter class allows you to convert arbitrary values into float using the following extended conversion rules:

• Strings are converted to float values
• DateTime: total number of milliseconds since unix epoch
• Boolean: 1 for true and 0 for false

Methods

ToFloat

Converts value into float or returns 0 when conversion is not possible.

ToFloat(value any) float32

• value: any - value to convert.
• returns: float32 - float value or 0 when conversion is not supported.

ToFloatWithDefault

Converts value into float or returns default when conversion is not possible.
See DoubleConverter.ToDoubleWithDefault,
DoubleConverter.ToNullableDouble

ToFloatWithDefault(value any, defaultValue float32) float32

• value: any - value to convert.
• defaultValue: float32 - default value.
• returns: float32 - float value or default value when conversion is not supported.

ToNullableFloat

Converts value into float or returns nil when conversion is not possible.
See DoubleConverter.ToNullableDouble

ToNullableFloat(value any) (float32, bool)

• value: any - value to convert.
• returns: (float32, bool) - float value and true or 0 and false when conversion is not supported.

Examples

value1, ok1 := convert.FloatConverter.ToNullableFloat("ABC")
value2, ok2 := convert.FloatConverter.ToNullableFloat("123.456")
value3, ok3 := convert.FloatConverter.ToNullableFloat(true)
value4, ok4 := convert.FloatConverter.ToNullableFloat(time.Now())
fmt.Println(value1, ok1) // 0, false
fmt.Println(value2, ok2) // 123.456, true
fmt.Println(value3, ok3) // 1, true
fmt.Println(value4, ok4) // current milliseconds (e.g. 1.566333114e+09), true
